P600 Methods for Testing the Performance of LEV


P600 is an introductory one-day LEV course.  It is is offered in both Webinar and Face-to-Face formats.  For some dates parallel courses are being run in both formats.

Webinars are conducted ‘live’ using the Zoom platform while face-to-face courses are normally held at the Hilton Hotel. Leicester.

Payment not required at checkout.  Invoices will be sent approx 5-6 weeks before the course.

OXYL8 Rubber Duck RoxxyThis entry level course enables delegates to identify and correctly use the appropriate LEV flow-visualisation and measurement techniques (LEV Test Instruments) ….. under  competent supervision.

The course focuses on the fundamentals of LEV systems.  It considers the standard component parts, measurement and testing techniques and equipment etc.


It provides delegates with the necessary skills and knowledge to improve their understanding of Performance Measurements in LEV.

For many this will act as a starting point in their progression towards a career in LEV.  P600 can be taken by newcomers to the field of LEV or by less experienced LEV personnel as part of their progression towards a Level 4 qualification, eg P601P604 series). P600 is a Level 3 course.

It does not confer ‘competency’ on the delegate to allow them to undertake stutory examinations and tests under CoSHH Reg 9.

In general terms – by attending this P600 delegates will gain knowledge and understanding of the:-

  • Basic components of local exhaust ventilation systems.
  • Methodologies for undertaking the performance testing of LEV equipment
  • Qualitative visualisation techniques (smoke release/’dust lamp’ etc).
  • Quantitative measurement techniques (anemometers, Pitot tubes etc).


Delegates wishing to attend P600Methods for Testing the Performance of LEV” Webinar/On-Line training course are expected to have some basic knowledge of LEV systems.

Please note:  P600 success does not confer ‘Competency’ for undertaking CoSHH Reg 9 TExTs unsupervised.


  • Basic components of local exhaust ventilation (LEV) systems (i.e. inlets, ductwork, air cleaners, air movers, ventilation hoods and discharges)
  • Use of smoke generators and/or smoke tubes to visualise air flows in and around LEV systems
  • Use of a dust lamp to visualise fine airborne dust
  • Using a pitot tube/manometer combination
  • How to carry out a Pitot tube traverse to determine static pressure (Sp), velocity pressure (Vp), and then to calculate the velocity in a ducted ventilation system
  • Vane and Hot Wire anemometers
  • How and where to undertake measurements in relation to the hoods (inlets) of an LEV system
  • Introduction to the maths used in Level 4 courses (eg P601 and P602) – note there is no maths in nthe exam
  • Choosing the appropriate test equipment and how to use it correctly


At the course conclusion there will be a short Multiple Choice Questionnaire (MCQ) examination comprising 20 questions.  The time allowed is 60 mins.

The exam will be marked by BOHS and on satisfactory completion of the MCQ, BOHS will award a “P600 Course Certificate“.


£375 (+exam fee £70*) + VAT / delegate

* Exam Fees reviewed by BOHS Jan each year


The P601 Thorough Examination & Testing of LEV Systems course is a natural follow-on from this course,


The P600 qualification may also meet some of the base requirements towards entry membership at the Society of Operations Engineers (SOE) and the Institute of LEV Engineers (ILEVE).
